Product details
Overview
6DFN15CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, featuring 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 21.2 V maximum clamping voltage (VC) at 28.3 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It protects signal lines in sensor units and MOSFET gate drivers against lightning-induced transients and inductive switching surges.
For engineers reviewing the 6DFN15CA-M3/H datasheet, 6DFN15CA-M3/H pinout, 6DFN15CA-M3/H application, or 6DFN15CA-M3/H equivalent, this page delivers verified electrical parameters, AOI-compatible DFN3820A package details, bidirectional clamping behavior, thermal resistance values (RθJA = 175 °C/W), and ESD immunity per IEC 61000-4-2 (±30 kV contact/air).
Technical Context
This TVS diode employs anisotropic rectifier technology with junction passivation optimized for low-leakage bidirectional clamping. Its DFN3820A package features side-wettable flanks enabling automated optical inspection and high-reliability solder joint verification.
It operates across -65 °C to +175 °C junction temperature range, meets MSL Level 1 per J-STD-020, and delivers 2.0 μA max reverse leakage at VWM and 6.0 μA at 150 °C - critical for low-power sensor interface protection where standby current integrity is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - ensures reliable conduction onset above 12.8 V system operating voltage without false triggering |
| VWM | 12.8 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA, compatible with 12 V rail interfaces |
| VC @ IPPM | 21.2 V at 28.3 A - limits downstream voltage stress during 600 W transient events, protecting 24 V-rated ICs |
| IPPM (10/1000 μs) | 28.3 A - peak surge current handling capacity under standard lightning waveform, derated above 25 °C |
| RθJA | 175 °C/W - thermal resistance to ambient on FR4 PCB defines safe power dissipation limit in compact layouts |
| ESD Rating | ±30 kV contact/air per IEC 61000-4-2 - enables robust electrostatic discharge protection without external shielding |
| Junction Temp Range | -65 to +175 °C - supports operation in automotive under-hood and industrial motor control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15CA-E3/5T | DO-214AC (SMA) package, 1.9 mm height, RθJA = 50 °C/W, VC = 24.4 V @ 24.5 A | Higher profile and lower power density; better thermal dissipation on open-board mounting but unsuitable for ultra-thin modules | Select when board-level airflow or heatsinking is available and AOI is not required. |
| SMCJ15CAHE3/57T | DO-214AB (SMC) package, 2.6 mm height, RθJA = 25 °C/W, VC = 24.4 V @ 43.3 A, 1500 W rating | Higher surge capacity and superior thermal performance, but incompatible with fine-pitch SMT lines and AOI systems | Choose for high-energy industrial motor drives where PCB real estate allows larger footprint and higher clamping voltage is acceptable. |
Compared with SMAJ15CA-E3/5T and SMCJ15CAHE3/57T, the 6DFN15CA-M3/H offers the lowest mounting height and AOI-ready side-wettable flanks - critical for miniaturized, high-reliability production - while trading off absolute surge energy handling for superior board-level integration and automated inspection capability.

FAQ
What is the breakdown voltage tolerance of the 6DFN15CA-M3/H?
The 6DFN15CA-M3/H has a ±5 % breakdown voltage tolerance, specified as 14.3 V (min), 15.0 V (typ), and 15.8 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in 12 V systems where the 6DFN15CA-M3/H is commonly deployed.
Does the 6DFN15CA-M3/H require a cathode marking for orientation?
No - the 6DFN15CA-M3/H is a bidirectional TVS diode with no cathode band or polarity marking. Its symmetrical internal structure means either terminal can serve as anode or cathode depending on transient polarity, simplifying PCB layout and eliminating orientation errors during automated placement of the 6DFN15CA-M3/H.
What is the maximum junction temperature rating for the 6DFN15CA-M3/H?
The 6DFN15CA-M3/H is rated for a maximum junction temperature of +175 °C and a minimum of -65 °C. This wide operating range supports deployment in under-hood automotive environments and industrial motor control enclosures where ambient temperatures exceed 125 °C, ensuring long-term reliability of the 6DFN15CA-M3/H under sustained thermal stress.
Is the 6DFN15CA-M3/H compatible with lead-free reflow processes?
Yes - the 6DFN15CA-M3/H uses matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and is rated for a maximum lead-free reflow peak temperature of 260 °C per J-STD-020 MSL Level 1. This makes the 6DFN15CA-M3/H fully compatible with standard Pb-free manufacturing flows without special handling or baking requirements.
How does the 6DFN15CA-M3/H perform under high-temperature reverse leakage conditions?
At TJ = 150 °C, the 6DFN15CA-M3/H exhibits ≤6.0 μA maximum reverse leakage at VWM = 12.8 V - only three times its 25 °C leakage (≤2.0 μA). This controlled thermal drift ensures stable protection margins in thermally demanding applications such as power supply monitoring circuits where the 6DFN15CA-M3/H maintains functional integrity across full temperature range.
